gas tank roblems

[hollywoodwayne]

swapped out some concrete work for some help in restoring a 1972 seacraft .They installed a new fuel tank and glassed the floor in.My engine will not pull fuel from this tank (aluminum) I have allready siphoned about 2 gallons of crap out of it until i,m getting nothing but clean fuel,changed my fuel water separator changed my inline filter,everythings clean.I can hook the motor up to a 6 gallon tank runs great,unhook from that tank and hook up to main tank,cant pull fuel.The tank is vented and when i blow compressed air into vent hose fuel comes out the hookup.When I try to run off main tank the inline filter just bubbles up like its gettin a vacuum. This is driving me crazy, can anyone HELP ???

i can't help but wonder if your vent is clogged. you'd have a vacuum then. no pump in the world would get that motor to run. just my opinion.

bypass the fuel filter see what happens. Make sure they installed 3/8th hose for pickup.
